A sterile, flexible, probe-like device intended to be connected to a surgical laser system to invasively direct and deliver laser energy for urogenital surgical applications, typically to haemostatically cut, coagulate, and vaporize prostate tissue to treat benign prostatic hyperplasia (BPH), and/or to treat bladder, urethral, and ureteral conditions (e.g., tumours, condylomas); it is not intended for other surgical applications. It is typically made of fibreoptic materials or fused silica and contains an invasive laser-firing distal end which may be available in a variety of configurations. This is a single-use device.
